Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.
[0016] Figure 1 It is a schematic diagram of the integrated clamping claw for AGV hoist of the utility model;
[0017] An integrated clamp 10 for an AGV hoist, a crossbeam frame 11, a drive motor 12, a rotating shaft 13, a forward screw 14, a forward nut 15, a reverse screw 16, a reverse nut 17, a driving gear 18, a driven gear (not shown), a synchronous belt 19, a guide rail 20, a clamp 21, a limit block 22, a photoelectric sensor 23, a first proximity switch 24, a second proximity switch 25, a coupling 26, a motor bracket 27, a rotating shaft seat 28, and a sliding block 29. DETAILED DESCRIPTION
[0018] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.
[0019] like Figure 1As shown, an integrated clamp 10 for an AGV hoist of the present application comprises: a crossbeam frame 11, which is installed on the hoist to be driven by the vertical drive mechanism on the hoist, so as to move up and down. A driving motor 12 is installed on the crossbeam frame 11, and a rotating shaft 13 is rotatably installed on the crossbeam frame 11. The two ends of the rotating shaft 13 are respectively connected to a forward screw 14 and a reverse screw 16. A driving gear 18 is fixed to the motor shaft of the driving motor 12, and a driven gear is fixed to the outer periphery of the rotating shaft 13. A synchronous belt 19 is sleeved between the driven gear and the driving gear 18. A guide rail 20 is installed on the lower side of the crossbeam frame 11, and two clamps 21 are slidably installed on the guide rail 20 for clamping a robot to carry the robot. Among them, one of the two clamps 21 is threadedly sleeved on the outer periphery of the forward screw through the forward nut 15, and the other is threadedly sleeved on the outer periphery of the reverse screw through the reverse nut 17.
[0020] Thus, when the hoist is started, the vertical drive mechanism of the hoist first drives the crossbeam frame 11 to the designated position, and then the drive motor 12 is started, and at the same time, the forward screw rod 14 and the reverse screw rod 16 are driven to rotate. Since the forward screw rod 14 and the reverse screw rod 16 rotate in opposite directions, the two clamping claws 21 can be driven to move in opposite directions, thereby clamping the robot to be transported. After the two clamping claws 21 clamp the robot to be transported, the vertical drive mechanism drives the crossbeam frame 11 to move downward to the ground. At this time, the robot to be transported falls to the ground, and the drive motor 12 rotates in the opposite direction to make the two clamping claws 21 return to the original initial position, and the clamped robot drives to the designated position by itself.
[0021] Specifically, the two clamping jaws 21 are provided with photoelectric sensors 23, which are communicatively connected to the drive motor 12. The light sensing of the photoelectric sensors 23 can detect the positions of the clamping jaws 21 and the robot to be transported, that is, the clamping jaws 21 are judged to have contacted the robot, and then the drive motor 12 is controlled to stop running, at which time the clamping operation is completed. Two photoelectric sensors 23 are provided on the two clamping jaws 21, and the two photoelectric sensors 23 on the same clamping jaw 21 are respectively arranged on both sides of the clamping jaw 21, so as to improve the accuracy of detection.
[0022] Furthermore, first proximity switches 24 are respectively provided at preset positions on both sides of the crossbeam frame 11, and the first proximity switches 24 are communicatively connected to the drive motor 12. When the first proximity switch 24 detects that the corresponding clamping jaw 21 has moved to the preset position, the drive motor 12 is controlled to stop running, so that the moving position of the clamping jaw 21 can be limited, thereby preventing the clamping jaw 21 from hitting the mounting components on the crossbeam frame 11.
[0023] Furthermore, a second proximity switch 25 is provided at the end of the crossbeam frame 11, and the second proximity switch 25 is communicatively connected to the drive motor 12. The second proximity switch 25 is used to detect the vertical position of the crossbeam frame 11, so that when the crossbeam frame 11 moves to a preset position, the drive motor 12 is controlled to operate to drive the two grippers 21 to disengage from the robot and return to their original positions.
[0024] The above-mentioned integrated clamping jaw 10 for AGV hoist adopts a forward and reverse screw structure for coaxial transmission, and is driven by a single motor. It has a simple and compact structure, high transmission efficiency, high consistency of lateral movement of the two clamping jaws 21, and higher clamping accuracy. At the same time, such a one-stage screw telescopic structure can not only meet the clamping requirements of any model of robot, but also has fewer parts and low cost.
[0025] As a specific implementation, limit blocks 22 are respectively provided at both ends of the guide rail 20 to prevent the clamping claw 21 from derailing.
[0026] As a specific implementation, both ends of the rotating shaft 13 are connected to the reverse screw 16 and the forward screw 14 through the coupling 26, thereby improving the effectiveness of the shaft transmission, extending the service life of the shaft, and reducing the torque on the transmission shaft.
[0027] As a specific implementation, the driving motor 12 is fixed to the middle of the crossbeam frame 11 through the motor bracket 27, and two rotating shaft seats 28 are provided in the middle of the lower side of the crossbeam frame 11. The two ends of the rotating shaft 13 are respectively rotatably mounted on the two shaft seats. Such an installation is convenient for individual disassembly and assembly of parts.
[0028] As a specific implementation, the guide rail 20 is a ball bearing slide rail, the lower side of the guide rail 20 is slidably connected with a sliding block 29, and the clamping claw 21 is fixed below the sliding block 29. Such a guide structure is smoother and can effectively reduce energy consumption.
[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
